Properly speaking, Nadav Rotem's Open Text Summarizer (OTS) is not a summarizer at all. True summaries generally involve rewording contents at a higher level of generality while preserving the meaning, not just producing a condensed version of the original the way that OTS does. However, within its limits, OTS is an efficient tool for automatically producing abstracts of non-fiction, that, in the last 15 months, has received favorable mention from at least four academic publications, including one in which it outperformed similar utilities, including commercial ones such as Copernic and Subject Search Summarizer.
